Abstract: A plant-growing container (500) can include a lower portion (506) and a wall (502) extending upwardly from the lower portion (506). The wall (502) can include a first aperture (512). The plant-growing container (500) can further include an orifice (510) formed by an upper portion (504) of the wall (502) and configured to receive a removable seed receptacle. The plant-growing container (500) can further include a reservoir provided by a lower portion (506) of the wall (502). The container (500) can be configured to be removably inserted into a port of a module of a plant-growing system, wherein the reservoir can be configured to receive a first volume of fluid from a fluid that is circulated through the plant-growing system.
